Assessment of Sticky Bone in One- Stage Lateral Sinus Lift Procedures: A 4 year Retrospective Study

This study aimed to assess the clinical and radiographic outcomes of using sticky bone in lateral sinus lift procedures combined with dental implant placement, and compare the clinical and radiographic outcomes between the perforated and non-perforated groups.

This retrospective study was conducted on individuals who presented to the Department of Oral and Maxillofacial Surgery at Tishreen University from September 2018 to September 2022. The sample included patients who had lateral sinus lift with simultaneous dental implant placement. The lateral sinus floor elevation procedures involved the use of sticky bone, a mixture of injectable platelet-rich fibrin, and bovine graft material. Bone height measurements were assessed using preoperative and 9-month postoperative CBCT scans. Statistical analyses were conducted to evaluate the Initial Bone Height (IBH), bone height after 9 months, and Intra-sinus Bone Gain (IBG). The intra-sinus bone gain outcomes were compared between perforated and non-perforated groups using an unpaired t-test.

In this study, 21 implants were inserted in 15 patients who underwent lateral sinus augmentation using sticky bone. Four membrane perforations were identified during 15 procedures (26.6%). The survival rate for all implants was 100%. The average intra-sinus bone gain was 5.54 ± 0.74 mm. There was no statistically significant difference in intra-sinus bone gain between the perforation group and non-perforation group (P>0.001).

Based on the findings of this study, sticky bone can be effectively used as a graft material to achieve bone graft survival and successful sinus augmentation in lateral sinus lift procedures with simultaneous dental implant placement, even following small and medium Schneiderian membrane perforation (<10 mm).
